Abstract

The present invention provides a polysilicon manufacturing apparatus that can prevent generation of popcorns in the entire CVD reaction process by cooling an upper portion of a silicon rod (40) where a rod bridge (31) is disposed. A polysilicon manufacturing apparatus according to an exemplary embodiment of the present invention includes: a reactor (10) provided on a base (21) and forming a reaction chamber (11); a pair of feedthroughs provided in the base (21) and extending into the reaction chamber (11); rod filament (30)s provided in the feedthroughs in the reaction chamber (11), connected with each other at upper ends thereof through a rod bridge (31), and where a silicon rod (40) of polysilicon is formed from a raw material gas through a chemical vapor deposition (CVD) process; and cooling spray nozzles spraying a cooling gas to the silicon rod (40) formed as silicon deposited around the rod bridge (31) and the rod filaments (30).
